In Depth Technosaurus is in simple terms a mess. Described in 1984 by Sankar Chatterjee from an astralgus (ankle bone), a dorsal (back) vertebrae, two lower jaws and a premaxilla, Techonosaurus was heralded as the earliest ornithischian (bird hipped) dinosaur of the time. Then in 1991another palaeontologist named Paul Sereno re-examined the fossils, a study … Read more
In Depth Fukuisaurus was initially only known from partial skull fragments, including a maxilla and jugal from the right hand side of the skull. Further specimens have since been discovered leading to Fukuisaurus being reconstructed with a strong degree of confidence. As an ornithopod, Fukuisaurus is similar to others of the group such as Iguanodon. … Read more
In Depth The creation of the Bellusaurus was born out of the discovery of a bonebed of at least seventeen individuals. Features on some of these fossil such as the lack of fusion on some parts means that these individuals are probably juveniles and therefore not fully grown. It has also led to speculation that … Read more
In Depth Navajodactylus was named in honour of the Navajo Nation with the genus name also incorporating the Greek ‘dactylus’ for ‘finger’, like in many other pterosaurs. The species name honours Arjan C. Boer� who discovered the holotype specimen in the Kirtland Formation back in 2002. Navajodactylus has been placed within the azhdarchidae pterosaurs, although … Read more
In Depth Originally described as a species of Aeolosaurus, A. maximus was established as its own genus, Arrudatitan, in 2021. Arrudatitan was established from partial remains including limbs, shoulder, hip and various vertebrae. Aside from being distinct from Aeolosaurus, Arrudatitan is noted for being fairly lightly built when compared to other titanosaur genera as a … Read more
In Depth The partial skeletal remains that the Drusilasaura genus is known by have been seen to be indicative of a lognkosaurian titanosaur. If this analysis is correct then Drusilasaura would be the oldest known lognkosaurian titanosaur. Further Reading – Drusilasaura deseadensis gen. et sp. nov., a new titanosaur (Dinosauria-Sauropoda), of the Bajo Barreal Formation, … Read more
In Depth Named after the famous palaeontologist Jos� Fernando Bonaparte for his contributions to the advancement of palaeontology, Bonatitan seems to have actually been quite a small titanosaur. Hailing from the Allen Formation, Bonatitan likely shared its habitat with other dinosaurs such as other titanosaurs like Saltasaurus, Laplatasaurus, Aeolosaurus and Rocasaurus and the hadrosaurs Lapampasaurus … Read more
In Depth There has been some contention over exactly what kind of theropod dinosaur Austrocheirus was. When described, Austrocheirus was identified as an abelisauroid theropod via cladistic analysis. This was significant because this would have been the first example of an abelisauroid theropod which did not feature the forelimb reduction which is often used as … Read more
In Depth Garrigatitan is a genus of titanosaur that lived in Western Europe during the late Cretaceous. Known only from partial remains of an immature individual, Garrigatitan seems to have been a fairly small titanosaur, even when fully grown. Further Reading - A new titanosaur (Dinosauria: Sauropoda) from the Upper Cretaceous of Velaux-La-Bastide Neuve (southern … Read more
In Depth Callawayasaurus was originally known as a species of Alzadasaurus until Kenneth Carpenter studied the remains and found that they actually represented a new genus. On a related note the type specimen of Alzadasaurus today only exists as a synonym to Thalassomedon and Styxosaurus. Carpenter named the new genus in honour of fellow palaeontologist … Read more
